This paper proposes a modified way to delimit the boundary of Busan metropolitan area and compares the empirical analysis with the existing metropolitan area boundary. More specifically, the present state of the metropolitan transportation network is reflected by service area analysis in our study area. The analysis of the linkage between the central city and its fringes considers various travel behaviors as well as commuting to work and school, based on origin-destination trip information. In addition, more diverse indices are applied to the analysis of urban characteristics, and the land cover map is used as well. Compared with the current Busan metropolitan area boundary, our empirical analysis captures the status quo of the undergoing spatial dynamics such as the newly form ed homogeneous sphere of living in our study area. 본 연구는 부산권을 사례대상으로 하여 보완된 광역도시권 설정방안을 제시하고 실증적인 설정결과를 현행 광역도시권 설정사례와 비교하였다. 분석의 공간적 대상선정과 관련해서는 네트워크 분석 기법의 하나인 서비스 권역 분석을 통하여 중심도시의 반경권이 아닌 광역교통망의 실제 분포를 반영하였으며, 중심도시와 주변지역 간의 연계성 분석은 기종점 통행량 자료를 사용하여 통근 통학과 더불어 업무 구매 여가 친교 등의 다양한 통행행위를 고려하였다. 또한 주변지역의 도시적 특성은 지표항목을 추가적으로 적용하고, 분석과정에서 토지피복지도를 사용하여 분석의 정확도를 높이고자 하였다. 본 연구에서 설정한 광역도시권의 설정범위는 현행 광역도시권 설정사례와 비교하여 일부지역에서 차이를 나타내며, 이는 인접한 지역 간에 새롭게 형성된 동질적 생활권의 양상이 반영된 점에 따른 것으로 사료된다.

본 논문에서는 완벽한 고장 효율을 보장하는 제어 회로를 위한 효율적인 비주사 DFT(design for testability) 기법을 제안한다. 제안된 비주사 DFT 기법은 순차 회로 모델이 아닌 조합 회로 모델에 대하여 ATPG(automatic test pattern generation)론 수행함으로써 짧은 테스트 패턴 생성 시간과 항상 완벽한 고장 효율을 보장한다. 본 논문에서 제시된 기법은 완전 주사 기법 및 기존의 비주사 DFT 기법들과 비교하여 적은 면적 오버헤드를 가지며 테스트 패턴을 칩의 정상동작속도로 인가할 수 있고, 또한 테스트 패턴의 재배열과정을 통해 테스트 패턴을 최소한의 시간으로 인가할 수 있도록 하였다. 제안된 기법의 효율성을 검증하기 위해 MCNC'91 FSM 벤치마크 회포들을 이용하여 실험을 수행하였다. In this paper, an efficient non-scan design-for-testability (DFT) method for controller circuits is proposed. The proposed method always guarantees a short test pattern generation time and complete fault efficiency. It has a lower area overhead than full-scan and other non-scan DFT methods and enables to apply test patterns at-speed. The proposed method also shortens the test application time through a test pattern re-ordering procedure. The efficiency of the proposed method is demonstrated using well known MCNC'91 FSM benchmark circuits.

Microbiomes are known to have a beneficial effect on human health by promoting the effective removal of improperly functioning immune cells and protecting the host from pathogen infection. On the other hand, these microbiomes are also known as the causative agent of numerous malignant tumors. Until now, the bladder has been regarded as aseptic, but the concept of the “sterile bladder” has been changed with the discovery of living bacteria embedded in the bladder with the recent development of polymerase chain reaction and culture techniques. This paper referred to the relationship between microbiome and bladder cancer. Microbiome will be able to be seen as a non-invasive biomarker to predict the success rate of intravesical bacillus Calmette-Guerin instillation treatment in patients of bladder cancer.

심재헌(Shim, Jae-Heon),김자은(Kim, Ja-Eun) 한국산학기술학회 2012 한국산학기술학회논문지 Vol.13 No.9

국내의 자연재해 관련 연구들은 토지이용관리를 통한 비구조적 접근이 재해저감에 있어 효과적인 수단임을 언급하고 있으나, 분석과정에서 토지이용과 관련된 미시적 접근은 극히 제한적으로 이루어져 왔다. 이와 같은 맥락에 서 본 연구는 공간상에 상이한 형태로 분포하는 토지이용특성들이 자연재해에 따른 피해액에 미치는 영향을 규명한 다. 실증분석의 결과를 살펴보면, 불투수지역 면적, 공업지역 면적, 나지면적, 하천면적 등은 자연재해 피해액에 유의 한 정(+)의 영향을 미치는 것으로 나타났으나, 제방시설의 면적은 자연재해 피해액과 강한 부(-)의 상관성을 가지는 것으로 나타났다. 이와 같은 결과에 기초하여 본 연구에서는 토지이용측면에서의 효율적인 자연재해 저감방안을 제시 한다. This study examines the effect of diverse land-use characteristics on the total sum of damages caused by natural hazards. The empirical results show that impermeable layer area, industrial land area, bare land area, stream area, and so on have a positive influence on damages, and that the area of levee has a strongly negative relationship with them. Therefore, this study strives to propose some efficient natural hazard mitigation ways in terms of land-use planning, based on our empirical findings.

심재헌(Shim Jae-Heon),조찬호(Cho Chan-ho),이성호(Lee Sung-Ho) 대한국토·도시계획학회 2007 國土計劃 Vol.42 No.5

The purpose of this study is to propose an industrial land price appraisal model using the error back propagation algorithm of the neural network theory to improve the current problem of applying uniform price without consideration of the location characteristic of individual plots. The neural network model using actual market prices and the characteristics of lands as input data is trained and the prices of industrial lands using data not included in the training is estimated. Compared with actual market prices, the prices estimated by the neural network model were not statistically different from the actual market prices. Lastly, as a limitation of this research, although it is desirable to use an extensive and large amount of input data, the scope of data is limited due to difficulties in data acquisition. Nevertheless, this study is considered significant in that it suggests the solution for a current problem and can be applied to existing and new studies on the price estimation of artificial neural network model.

Lastly, the sites of six stores are evaluated relatively, then the optimal location is selected, which proves the applicability for decision making process this study suggests.

입지특성을 고려한 토지가격의 차등적 산정방안 : 산업시설용지 공급가격을 중심으로

심재헌(Shim Jae Heon) 대한토목학회 2011 대한토목학회논문집 D Vol.31 No.2D

본 연구는 지가산정을 위한 방법론으로 서포트 벡터 회귀분석(SVR)을 이용하여 입지특성에 근거한 산업시설용지의 차등적 가격산정모형을 제시하고자 하였다. 기업의 생산활동을 위한 산업시설용지의 공급가격은 용지부담금, 조성비, 판매 및 관리비, 자본비용 등으로 구성된 조성원가를 바탕으로 책정된다. 그러나 현행 산업시설용지 공급가격 산정방식은 개별적인 용지의 입지여건을 고려하지 않은 채 동일한 가격을 단지 내 모든 용지에 획일적으로 적용하는 불합리성을 내포하고 있다. 따라서 본 연구는 이를 지양하기 위한 방안으로 산업시설용지의 차등적 가격산정모형을 제시하고, 모형의 적정성 및 실무적인 적용가능성을 평가하는 과정으로 이루어진다. This paper proposes a differential pricing model for industrial land based on locational characteristics, using Support Vector Regression (SVR) as a land pricing methodology. The initial selling price of industrial land is set based on the total cost of site development that comprises the land acquisition cost and tax, land development expense, infrastructure installation cost, labor cost, migration expense, selling and administrative expense, capital cost, and so on. However, the current industrial land pricing method unreasonably applies the same price per square meter to all parcels within an industrial complex without considering differences in price depending on the location of each parcel. Therefore, this paper proposes an empirical land pricing model to solve this irrationality and verifies its validity and applicability.

포아송 위계선형모형을 활용한 인구이동 실증분석

심재헌(Shim, Jae-Heon) 대한국토·도시계획학회 2012 國土計劃 Vol.47 No.2

Since migration causes socio-economic and population changes in urban area, it is considered a significant factor in forecasting demands in a number of urban socio-economic categories. In spite of its importance in planning, however, the existing model lacks in comprehensive explanation of the origins (from where) of migration, the destinations (to where), whom, why, and by how much volume migration takes place inter-regionally. This study is designed to develop a mirgration model for analyzing and forecasting inter-regional migrations, concerning selectivity and determinants of migration which are affected by spatial heterogeneity. In this research, migration model is classified into three levels: Level 1) gender and age-group inter-immigration locations divided by destination; Level 2) by different migration location within an area; and Level 3) by city and gun regional level. Analyzing this model, a hierarchical generalized linear model is employed with consideration on Poisson distribution. Due to spatial effects in level 3, these variables have space-specific effects whose influence become high or relatively low in a specific location. Finally, compared to the existing model, this models forecasting quality of gender and age-group migration was precise enough to be used in the real-world urban and regional planning.
